I've not seen this, but previously used things like etags in C.
(cscope is also a great tool in this regard, but for C only).
It sounds interesting.

I'd be interested in pursuing this sometime...

(And, as a reminder, there is a simple example regexp for S functions
listed in the ESS manual, i.e.

     etags --language=none
     --regex='/\([^ \t]+\)[ \t]*<-[ \t]*function/\1/' *.R
